Calendar module won't show all events

  • The default calendar module connects to my iCloud calendars fine, but won’t show all events. I switched to MMM-CalendarExt and it shows perfectly.
    After the recent update of MagicMirror, MMM-CalendarExt won’t display on screen at all. I just need one of them to work properly. Any ideas?

    Look into issue:

    It is a problem of Electron that has been downgraded.

    The default calendar module has had some issues removed in the update, maybe it is now okay for you.

  • This is what I found out.


    Here’s the code at that location:

    addCalendars: async function() {
        var self = this
        for (var c in this.CurrentConfigs.calendars) {
          await sleep(1000)

    Could it be that the error is within the core programming of the module?

  • I’ve had the same problem since upgrading to MagicMirror 2.2.0.

    It seems that Node.js is upset that MMM-CalendarExt uses an async function at MMM-CalendarExt.js:182. From what I can tell, Node.js didn’t support async until 7.4, and I’m (apparently) running 6.12.2 (via node -v). However, until I upgraded MagicMirror this weekend, MMM-CalendarExt was working fine.

    I just edited to the following, and just got MMM-CalendarExt working again:

    electron --js-flags="--harmony-async-await" js/electron.js $1

    Can someone explain why upgrading to MagicMirror 2.2.0 would’ve rolled back the Node.js support for async?

    Nice. Thanks for the workaround! It’s working now.

    Slick fix, Well done. Think this should get pushed to the master branch? Does not seem it will get in the way of other functionality/stability since we can still use the lower electron version but obviously the workaround means updates involve stashing changes and such.

    It’s a great fix for this issue. Anyway, I’m almost finishing my vacation and my current business a few days. I should have to join the summit for business in mid of January in Seoul and Paris. After that, I will release fix of this issue.
